Abstract

The invention discloses an extraction agent and detection method for soluble substance content detection of an elastomer modified asphalt waterproof coiled material, and belongs to the technical fieldof building material detection. The extraction agent comprises ethylene glycol dimethyl ether and saturated alkane, the saturated alkane is one of n-hexane or 2-methylpentane, and the mass ratio of the ethylene glycol dimethyl ether to the saturated alkane is 1:(4-1); a mixed solvent of the ethylene glycol dimethyl ether and one of the n-hexane or the 2-methylpentane is adopted as the extractionagent instead of trichloroethylene, the experimental results and repeatability which are similar to the experimental results and repeatability of trichloroethylene are obtained, all components are non-toxic or low-toxic and environmentally friendlier, the extraction rate of a SBS modified material in the waterproof coiled material is high, and the extraction time is shortened effectively.

Description

technical field

[0001] The invention belongs to the technical field of building material detection, and in particular relates to an extraction agent and a detection method for detecting the soluble content of elastomer-modified asphalt waterproof coiled materials. Background technique

[0002] Elastomer (SBS) modified asphalt waterproof membrane implements the national standard GB18242-2008 "Elastomer Modified Asphalt Waterproof Membrane", which is coated with styrene-butadiene-styrene (SBS) rubber modified asphalt. It is an excellent waterproof material made of glass fiber felt, polyester felt and glass fiber reinforced polyester felt as the base, and isolating material on both sides. It has heat resistance, cold resistance, corrosion resistance, aging resistance and good thermoplasticity. , high tensile strength, high elongation, strong tear resistance and other advantages.

[0003] Soluble matter content is an important index to judge and distinguish the quality of elast...
